Rachel DiCarlo's article, Spoiling Some of the Fun, fails to address
why Libertarian candidates are able to "spoil" the campaigns of
Republican candidates. The culprit is the first-past-the-post,
winner-take-all electoral system used in most U.S. elections since the
country's founding.

Libertarians have had no role in perpetuating the winner-take-all
system, which according to Duverger's Law creates two strong political
parties and marginalizes the rest. Indeed, Libertarians have advocated
the adoption of electoral systems successfully implemented elsewhere,
such as "preferential voting" (a.k.a. "instant runoff voting"), that
won't break down when more than two candidates compete and would
prevent the spoiler problem. But even though they proposed and endorsed
the idea, Republicans in Alaska couldn't get together to pass an IRV
measure when it came up for a statewide vote earlier this year. Indeed,
several Alaska Republicans argued self-servingly that plurality rule
was just fine by them, especially when their candidates won.

Understandably, many Republicans and Democrats are content with an
electoral system that protects their two-party duopoly from meaningful
competition and keeps non-incumbent political parties out of office.
Republicans and Democrats have made and maintained this Procrustean
electoral bed that they now claim tortures them. Until they put in
place electoral systems that accommodate more than two political
parties, I won't be very sympathetic to their complaints about being
"spoiled."

I've thought about the issue of election spoilers a lot. And yes it
burns both ways to the Republicans Rachel DiCarlo mentions, and
obviously to Democrats.

Maybe we need a run-off system. In the first election, you can vote for
who you really want. It might even propel Libertarians, Greens, and
other third party candidates to 2nd place finishes, and into the
run-off. Then in the run-off election, you simply vote for the one that
you dislike the least.

Of course this approach might help Republicans, who would probably do
better in run-offs than most Democratic candidates. This happened with
the late Georgia senator Paul Coverdell. He won his seat in the early
90s in a run-off when he failed to get 50 percent in the general
election. We'll see if this pattern hold up in Louisiana on Dec 7.
